Down Boy! (Kill processes by Port)

#kill #port #pid #process

Need to kill processes by port? Try this...

Cute dog

Setup

Save this bash script as downboy to your bin directory:

#!/bin/bash for PORT in $@ do PID=$(lsof -i :$PORT | awk 'FNR ==2 {print $2}') echo "kill -9 $PID" kill -9 $PID done
Enter fullscreen mode Exit fullscreen mode

Make downboy executable:

chmod +X ./downboy
Enter fullscreen mode Exit fullscreen mode

Usage

Now you can easily close any number of processes by their port:

sudo downboy 80 8080 3000
Enter fullscreen mode Exit fullscreen mode

Bye-bye.

Back in the mists of time, I recall that either the IRIX or Solaris implementation of fuser had the ability to kill processes by port.

Will save a lot of ps -ef | grep on my machine - I needed this, thanks!
